Guess the answer for this rebus (game rules below).

EDIT: The contest is over and no one guessed the official answer. 1 SBD was split between 4 replies officially recognized as alternative answers. Big thanks to all the participants! The solution (and some bonus) is available here.

Game rules:

The first person to find the official answer is the winner.
The winner receives 50% SBD from this post (or 1 SBD if the 50% would be less than that)
After 24 hours from the publishing of this post, the game ends and if no one guessed the answer, the prize will be unavailable - you can still guess for fun or click the link that I'll provide to see the answer
Resteem this post before the contest ends to receive 0.02 SBD - let me know in the comments that you reposted!
Alternative solutions are appreciated and may be rewarded with a special prize, but the official answer is required to become a winner

Read my post What is rebus? - examples that won't hurt you (no more) to learn about rebus puzzles and how to solve them.

EDIT - Three clues to help you going:

Hive account@james-show pointed out correctly that the H on the picture is obvious. This letter is extremely important and other writings on the wall don't matter.
The position of the letter H in the picture is very important.
See this article for inspiration. The basic idea here is quite similar. The answer has 10 letters (sometimes written as one word and sometimes as two) and begins with H.

Have fun! 😃

Congratulations to Hive account@james-show, the winner of the previous edition. He said he was a first timer, but it turned out that he pretty quickly took a matter of providing nice rebuses to Steemit audience into his own hands. Check his profile for the puzzles. The first three are already solved, but I hope there will be more!

Follow me to be sure that you won't miss the next edition!
